rename either the function or the class.
class Display_Records {
function display_records($row, $record_count) {
$current_date = (date("Y-m-d"));
$age = ($current_date);
return $age;
}
function disp_rec($row, $record_count) {
$current_date = (date("Y-m-d"));
$age = ($current_date);
return $age;
}
}
$d = new Display_Records();
// no problem here
print $d -> disp_rec('row', 'record cont');
// big problem here
print $d -> display_records('row', 'record cont');

> I have a function that works perfectly (from within a script). But when I
> make it a class (object) and call it from an external file, I get the
> following error:
>
> Warning: Missing argument 1 for display_records() in
> http://www.friendshipcenter.com/Objects/display_records.inc on line 5
>
> Warning: Missing argument 2 for display_records() in
> http://www.friendshipcenter.com/Objects/display_records.inc on line 5
>
> After the warnings, it executes the function without passing values to the
> variables (i.e., it doesn't work), and then it executes the function a
> second time perfectly (with the appropriate variables).
>
> Line 5 is this:
>
> function display_records($row, $record_count)
>
> It displays the first error message for $row, and the second error message
> for $record_count.
>
> I call the function with this:
>
> $my_records = new Display_Records;
> $my_records -> display_records($row, $record_count);
>
> The full scripts are below.
>
> What I tried that didn't help was declaring the variables in the class with:
>
> class Display_Records {
>
> var $row;
> var $record_count;
>
> I also tried setting defaults for the variables (er, attributes) with this

>
> $my_records = new Display_Records;
> $my_records -> row = $row;
> $my_records -> record_count = 1;
> $my_records -> display_records($my_records -> row, $my_records ->
> record_count);
